XABR-010

Air bushings can be used in different versions: if on the one hand, self-alignment gradually decreases, on the other hand, stiffness and then guides accuracies increase. They can be summarized as follows:  

  • RFF FLOATING VERSION

The sealing O-rings act as a spring and allow the cylindrical bearing to self-align to the guide element, and to help compensation of straightness and parallelism errors (within certain limits) as in the case of systems with 2 or more parallel shafts  

  • RFI STIFFENED FLOATING VERSION

The sealing O-rings also act as a spring, but, supplying compressed air in the resin room, the OR stiffen and allow less elasticity in the self-alignment  

  • RFR RESIN STIFFENED VERSION

The resin process leads to a rigid coupling, not self-aligning: in case of very slight misalignment of the guide shafts, it still guarantees the best alignment of the cylindrical bearings during the resin drying process
